Patent number: 8067078Abstract: The present invention relates to a novel composite structure with enhanced toughness, which incorporates features mimicked from nacre (mother of pearl). The structure can be used in many industrial and clinical applications, including aeronautics (aircraft skin), the defense industry (armor materials); orthopedics and medical devices (tough, biocompatible coatings on prostheses) and micro-electro-mechanical systems (MEMS; increased reliability for critical components).Type: GrantFiled: November 13, 2007Date of Patent: November 29, 2011Assignee: Northwestern UniversityInventors: Horacio Dante Espinosa, François Barthelat

Publication number: 20110277474Abstract: Provided herein are methods and systems for sequestering carbon dioxide from a multi-component gaseous stream, such as flue gas from natural gas-burning power plant to produce a protonated carbonate. Also provided herein are methods and systems for electrochemically producing proton-removing agents to form a deprotonated carbonate from the protonated carbonate. The electrochemical process may consume less energy than the amount of energy generated during production of the multi-component gaseous stream.Type: ApplicationFiled: June 10, 2011Publication date: November 17, 2011Inventors: BRENT R. CONSTANTZ, Ryan J. Gilliam

Publication number: 20110239906Abstract: New photocatalytic product comprising compounds of titanium integrated with limestone. The product is obtained by reacting limestone with a suitable precursor of titanium dioxide in a basic solution, followed by accurately washing the solid obtained, drying it and calcining it. A composite is obtained containing limestone, titanium dioxide and calcium titanate. The composite thus obtained, used as such or in mixture with other components, has shown an unexpectedly high photocatalytic activity.Type: ApplicationFiled: July 31, 2009Publication date: October 6, 2011Inventors: Renato Ancora, Massimo Borsa, Maurizio Marchi
